Title: An incinerator
Inventor: SHERRATT RICHARD ERNEST
IPC: F23G1/00
Filed: 1992-03-11
Abstract: An offal incinerator comprises a refractory brick lined body (1) with a chimney (3) connected to the body (1) at one end and vent means at the other end. A gas burner (33) is located at the same end of the incinerator as the chimney (3) and a fan (35) may blow air or oxygen into the body (1) to assist burning of offal. Hot air circulates within the body and passes over a stainless steel baffle (40) before passing up the chimney (3). The baffle (40) is at red heat due to the burning, and contact between the baffle and the hot air causes secondary burning of the hot air which destroys smoke particles. Remaining smoke particles are destroyed in afterburner (72). After the offal has been partially burnt, the gas burner (33) may be switched off while the fan (35) continues to operate. The offal may continue to burn long after the gas burner (33) has ceased to operate. <IMAGE>

Patent GB-2258600-A (GB)
Title: Preparation of soft dog chews
Inventor: CHIKAZAWA OSAMU
IPC: A23K1/18
Filed: 1992-08-07
Abstract: The invention comprises a substance and a method of manufacture of said substance whereby a cow's raw hide is cut into suitable shapes which are then dried and hardened before being heated and subsequently vacuum expanded to produce a soft dog chew. Although the resultant substance is made of the same materials and has the same taste as a conventional hard dog chew, the chew itself is in fact soft which means that it can be chewed to produce all the benefits that are normally required of a dog chew without at the same time damaging the weaker teeth of a puppy or of an old dog, for example.

Title: Encapsulated mesh heat exchange element
Inventor: DAVIDSON MAXWELL WINGATE
IPC: F28F21/00
Filed: 1992-12-11
Abstract: A heat exchange element comprises a composite wall member 9 made of metal mesh 10 and an encapsulating layer 11 of a material of lower thermal conductivity which envelopes and extends through the mesh, the layer thickness outside the mesh being substantially less than the thickness of the mesh so that the mesh extends substantially to, and conducts heat from, the outer surfaces of the wall member. The mesh may be interwoven metal strands or strips or be of pierced and expanded, preferably flattened, metal sheet. In one form immediately next to the mesh the encapsulating layer is a filled plastics material to promote heat capacity and outside the mesh the layer is of a corrosion resistant inert material. At least some of the mesh extends directly throughout the major part of the length and breadth of the wall member. The element may include a peripheral bead (5A, Figure 4). <IMAGE>

Patent GB-2267135-A (GB)
Title: Master cylinders for hydraulic braking systems
Inventor: ANDERSON ROBERT ALAN
IPC: B60T11/232
Filed: 1993-05-21
Abstract: A recuperation valve (11) of the centre valve type comprises a valve head (13) at one end of a stem (12), and the stem (12) comprises two parts (12, 25) which are relatively rotatable to adjust the effective length of the stem and the spacing between two abutment members (17, 21) forming abutments for opposite ends of a helical spring (26). Adjusting the length of the stem enables the valve clearance to be set within close limits before the valve is assembled to a respective piston (3, 4). This is achieved by use of a non-circular formation (14) to hold the stem (12) against rotation whilst rotating the part (25) which comprises the head of a screw. <IMAGE>
Patent GB-2268620-A (GB)
Title: Security starter batteries for automotive vehicles
Inventor: GATEHOUSE PETER PHILLIP
IPC: B60R25/045
Filed: 1993-06-25
Abstract: A battery has an exposed negative terminal 2, positive terminal 10 hidden within the battery casing, an exposed dummy terminal 3 and a control circuit including a heavy duty switch eg. soleniod 9 between the positive and dummy terminals and sealed within the battery, the control, circuit having an input for connection to an external code-controlled operating device for controlling the enabling of the switch. The positive terminal 10 may be connected through isolator relay 12 to an INHIBIT circuit C, such that when ignition is switched on power is fed to a keypad and only if predetermined code has been set into the keypad in order to pass is an operating signal passed to electronic lock 13 to switch the relay 12 to connect power to an ENABLE circuit B and to disconnect the supply from the INHIBIT circuit C. This causes solenoid 9 to operate to connect positive terminal 10 to the dummy terminal 3. When the ignition key is moved to the start position power is supplied to a starter motor. <IMAGE>
Patent GB-2268009-A (GB)
Title: Pulse Welding
Inventor: TABATA YOICHIRO
IPC: G05F1/08
Filed: 1993-09-14
Abstract: The welding current waveform is formed by superimposing groups of current pulses ion a continuous base current IB. The pulse amplitude in a pulse group may increase to a certain point and then decrease Fig. 5A. Such point corresponds to droplet separation or short/arc transition and may be determined by a timer (Figs. 1, 2) or by a droplet separation detector (Fig. 41). Alternatively, pulse width or pulse frequency may be varied within a group (Figs. 5B, C). Each pulse group may be terminated by a pulse group charge measuring device when the charge amount after droplet separation reaches a preset level, (Figs 9, 46). Pulse repetition period in a pulse group may be dependent on welding wire speed after, or both before and after, droplet separation, the period before separation being shorter than that after in both cases, (Figs. 12). Pulse width may be similarly varied and dependent on wire speed (Figs. 16, 18). The pulse group may have a triangular envelope with the slopes of the rising and falling sides being dependent on wire speed and average welding voltage, (Figs. 21-23); for short circuitry welding the slope of the envelope after short/arc transition may be similarly dependent, (Fig. 26). Pulse amplitude may be controlled by comparison of arc length with target arc length, (Figs. 46-49). In other embodiments there is no grouping of pulses, but the envelope or duration of individual pulses each corresponding to such a group is similarly varied, Fig. 5D, (Figs 6-8, 50B, 51B). <IMAGE>

Title: Laser radar system
Inventor: LIPCHAK JR W MICHAEL
IPC: G02F1/1343
Filed: 1991-11-08
Abstract: A laser radar system has an optical beam steering device (50) which provides deflection of the transmitted (44) and received (46) beams in two planes, while maintaining the distinctive identities of each channel respective to their polarizations. A beam (44) to be transmitted passes through a beam splitter (70), a Brewster angle plate (72) and the steering device (50). The beam splitter (70) diverts a local oscillation beam to a mirror (80) followed by a half-wave plate (84), a beam combiner (76) and a detector (64). A reflected beam (46) from a target passes through the device (50), is reflected by the Brewster plate (72) and the beam combiner (76), and impinges on the detector (64). <IMAGE>

Title: Difference recording apparatus and method
Inventor: WATANABE KIOSHI
IPC: G06F11/14
Filed: 1995-05-22
Abstract: A difference recording apparatus includes a log comparator (31), a processing unit (3), a recording unit (4), and a log update section (32). The log comparator detects a log difference by using a classification key (42) in a log of input data. The processing unit restores the log by using difference data from the log comparator (43). The recording unit records the log restored by the processing unit. The log update section limits recording of a log of identical data in the recording unit within a unit time on the basis of the presence/absence of a difference detected by the log comparator and an upper limit of log acquisition. <IMAGE>

Title: Electronic waveform generation of voiced audio tones
Inventor: PEERS JR ROI N
IPC: G10H5/02
Filed: 1995-09-01
Abstract: A tone generator clears all registers in a twenty-nine stage device so that the previous results are not used in the calculations for a next tone sample. A series approximation of a desired complex sound waveform is achieved by calculating the contributions of twenty-nine time steps back in time. Twenty-nine different address phases are X1 - X29 respectively applied to twenty-nine stacked arithmetic units. The output of the twenty-ninth unit produces the desired tone without any of the stacked units feeding back any signals. <IMAGE>
